In addition, commercial oil stocks in the United States have been at their lowest level in three decades. Total crude oil inventories, which include commercial and stocks in the Strategic Petroleum Reserve (SPR) are relatively low, in terms of daily coverage. Current commercial inventories are near the level at which spot shortages can occur. The past decade has seen scenarios in which the decline in commercial stocks is greater than the increase in the Strategic Petroleum Reserve, and the capacity of the Strategic Petroleum Reserve and commercial stocks to deal with a crisis is less than before the refilling program began (Williams and Alhajji, 2003). Moreover, the premature release of crude oil from the Strategic Petroleum Reserve can jeopardize national security in case of continued political problems in the oil-producing countries and weakens the ability of the United States to respond to real shortages.
Although some of the oil-importing countries have made progress in reducing their dependence on oil, the dependence of the United States on crude oil has increased in recent years from 38% of total energy consumption in 1995 to approximately 40% at the current time. This indicates two possible areas of concern regarding the extent to which crude oil influences energy security: (i) the increase in the crude oil share of energy use, and (ii) the inability or unwillingness of the United States to reduce dependence on imported oil.
